A "firebomb" was thrown into a Springdale home Sunday evening, police said.

Springdale officers reported the attack occurred around 5:30 p.m. in the 500 block of Grandin Avenue. The suspect remains at large.

Tom Lindsey, chief fire inspector for the Springdale Fire Department, said the woman who owns the house and her adult son were sitting down to dinner when they heard a noise outside. Before they could get outside, there was a flash in the living room.

A front window of the home was broken when something was thrown into the house. Whatever it was, it ignited and set some items inside on fire.

The son ran outside, where he confronted the alleged attacker, who fled. The owner's son went back inside and was able to put the fire out with a fire extinguisher. No injuries were reported and the fire was out when firefighters arrived.

A neighbor called police and reported the attack.

The 911 caller said a silver and blue Dodge Dakota truck with a man driving was seen leaving the scene.

Lindsey said the neighborhood is generally quiet. He said investigators have no leads as to a motive and the police and fire departments will conduct a a joint investigation.
